Artemis 1 is the first NASA mission Artemis program From the moon exploration. It will use the SLS megarocket to launch the unmanned Orion capsule on a long journey into lunar orbit and back.
NASA attempted to launch Artemis 1 on August 29 and September 3 but was aborted due to glitches both times. September 3 release was a liquid hydrogen fuel leakwhich the mission team addressed by replacing two seals in the damaged area, a “quick disconnect” connecting the SLS core stage to a fuel line from the portable launch tower.
The Artemis 1 team conducted a refueling test on Wednesday (September 21), and the repair was made; The team discovered a leak but was able to bring it down to manageable levels. All goals were met during Wednesday’s test, so “teams are adjusting procedures for the next launch opportunity, targeted no later than September 27,” according to NASA officials. wrote in the update (Opens in a new tab) Thursday (September 22).
Today’s press briefing will provide us with more details on these actions and the mission team’s plans moving forward.
These plans depend on several factors in addition to repairing the leak. For example, NASA has applied for a waiver from the US Space Force to extend certification of the Artemis 1 Flight Termination System (FTS), which is designed to destroy the SLS if something goes wrong during launch. (The Space Force oversees the eastern range of missile launches.)
The FTS has been approved for 25 days and this deadline has passed. If the waiver is not granted, NASA will have to return the Artemis 1 stack from its launch pad at the Kennedy Space Center in Florida to the facility’s massive vehicle assembly building for re-certification.
Then there’s the weather, which is always a concern on Florida’s hot and windy Space Coast.
